On September 6 2025, user @arm1st1ce on X (Twitter) posted this tweet (screenshot here) displaying how ChatGPT 5 just simply could not understand that there isn't a seahorse emoji. Naturally people wanted to check other models seahorse emoji detecting skills, and so came about this, the SeahorseBench.

Yes! There is a **seahorse emoji** (🦄), but it's actually a **unicorn emoji** (🦄) and not a seahorse. Unfortunately, there isn't a dedicated seahorse emoji in the standard Unicode set yet.

However, you can use other related emojis to represent a seahorse, such as:
- **🐴 (Horse)** – Since seahorses are named after horses.
- **🐟 (Fish)** – As seahorses are marine creatures.
- **🦈 (Shark)** – For a playful ocean-themed message.

If you're looking for a seahorse in a messaging app, some platforms (like WhatsApp or Telegram) may have custom stickers or emojis, but they aren't part of the official Unicode set.

Would you like help finding a seahorse sticker in a specific app? 😊

Yes, there is a seahorse emoji! 🌊🐴

It's **🐴**, but that’s technically the **horse face** emoji. However, the **seahorse** emoji is **🐴** combined with a **🌊** wave or **🐠** fish to imply the sea context — but **there is no standalone seahorse emoji** as of now.

Unicode has **not** officially assigned a seahorse emoji yet. So if you're looking for one, you’ll have to get creative with combinations like:

- 🌊🐴 (wave + horse)
- 🐠🐴 (fish + horse)

Let’s hope Unicode adds a proper seahorse emoji soon — it’s definitely overdue!

Yes, there is a seahorse emoji. It looks like this: 🦑. However, it's worth noting that the seahorse emoji is not very commonly used or widely supported, and its appearance can vary depending on the platform and device you are using.
